Application tiled september@ 1925,.. ,isgrdalajmod The invention relates to motor vehicles `and 4l'fers more .panticularly to improved means @forming a connection between. the Pump fand the ,cylindergjacket. Y

5 One of .the objects of 'my invention .is to provide a connect-ionoif the character afore-` said which is of simple constructiomcheaply -manuifactured and capableof;1`ready asseI-nbiy or replacement ofparts. A further `feature 1.0 resides in .providing afconnectionofa yielding or iiexible character whereby v:the generator which is commonly `ycanried as a .unit withqthe fpumypimay be readily `adjusted `for loosening or' :tightening I"the `chain ordinarily l5 `prevailed "Fior driving the lgenerator and "With vthese and r,other objects .in anew, the

invention resides inhthe novel @features of construction and `.combination and arrangements of ,parts asmore fully hereinafter'rde- `scribed and claimed. l j

Referring to the accompanying drawings yin Iwhich "like reference characters indicate `corresponding pants-` Fgurel is a ,plan view showing my in-.

vention applied to a cylinder Waterfjacket;` v I*`igure2 isla sectional .elevation 4.view ilf lustrating the parts forming the connection between Jtheepumpfand water cylinder; 80 Figure 3 is a perspective view showing in detail one form of the arts and forming the pump and water cylin er connection;

Figure 4 is a longitudinal elevation view in lcross section illustrating a modified conu struction ofpump connection.

In the drawings reference character 10 represents a cylinder water jacket, 11 the `water pump driven through a chain 12 and shaft 13. 14 is the generator also driven from the shaft 13. It is customary to drive both the water pump and generator through a common shaft and as shown in the dra-wings, to mount these members as a common unit. In order that the tension in the driving i4 chain 12 may be regulated, it is desirable to provide means whereby the pump and generator unit may be moved so as to change the position of the shaft 13.. Such an adjustment may be provided by forming the pump and generator unit with a fianged portion 15 adapted to be slidably adjustable against.

the face 16 of the housing for the chain 12. To this end therpump and generator unit may be pivotally connected to the Achain u casing 17 as shown'at 18. The Harige 15 may y of the generator.

` also be provided -niththe 1:51am` 19 L@at on an arc about the pivot point 18 and adapted to receive the cap -screws 20.which adjiustably -clamp the flange .-15 tothe face 16 of'the chain:casing 17.. 2:11am set screws for vfacilitating in .the adjustment of the generatdr unit. y

In o erationof ltheiparts as `thus far ldescribe Whenit is desiredto effect an fad- ,justmcnt Lof -the,.tension inthe chain ,12, the

three cap screws indicated `at 18;and20 are `lloosenedand the 4set screws v251 rotated to move the pump Iand generatorvun-itthe desired amount with respect tothe .chain casing 17. Then lthe cap screws aregtightened toclamp the unit in afixedposition.

In order to accommodatefor this adjust-` yment yof the generator it isapparent .that some means -must be provided foivperniitating Lrelative movement between tthe water pump 11 and the cylinder water -jacket 1Q.: To this end I have for-med thel pun-1p 11W-ith the terminal `flan-ge `22 provided Vwith the bolt openings 23.y accommodating the fbolts 24.

.25 1indicates' a Aconduit member forming-'the friction connection between the spump @andi cylinder Water-jacket. This member is gpref# `erably formed with fone or ,more bellows- ...like or return-bent portions 26 for gnendeiznig the conduit member iiexible. 27 is an end clamping disc engageable by the bolts 24 for clamping one end of the conduit member f between the disc and pump ange 22; 28

is a second end clamping disc engageable by the fasteners 29 for clamping the other end of the conduit member between the cylinder v Water jacket and the disc 28. The conduit member 25 is preferably formed of a rubberlike or relatively thin copper material.

. It will be noted that I have provided a simple means for forming aV iexible conduit between the water pump and cylinder Water jacket,.this conduit permitting adjustment It will further be noted that the parts may be readily assembled and when it isdesired to renew the conduit member 25 thelatter may be readily replaced by removing the end clamping discs 27 and 28. Where the conduit member is formed of relatively thin copper, I may formthis member as shown in Figure 4. In this figure the conduit member 25 maybe lprovided as before with the bellows-like, or return-bent portions 26', the ends of thel member 25 being soldered at 30 to the end clamping discs 2T and 2S. These end clamping discs as before, maybe respectively attached to the pump flange and the cylinder water jacket.

While it is believed from the foregoing description, the nature and advantage ot' my invention will be readily understood, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of the claims.

iVhat I claim as my invention is:-

l. The combination with a motor vehicle engine provided with a pump, a generator, and a cylinder water jacket, the said pump and generator being adjustable as a unit with respect to the cylinder water jacket, of a yieldable connection between said pump and jacket, the said connection including ay collapsible conduit.

2. The combination with a motor vehicle engine provided with a pump, a generator, and a cylinder water jacket. the said pump and generator being adjustable as a unit with reapect to the cylinder water jacket. ot a connection between said pump and jacket, comprising a jvielding conduit member and end clamping members adapted to respectiveljY clamp the respective ends of the said member between the clan'iping members and the pump and jacket respectively.

3. The combination with a motor vehicle engine provided with a pump. a generator, and a cylinderI water jacket7 the said pump and generator being adjustable as a unit with respect to the cylinder water jacket, of a connection between said pump and jacket comprising a yielding conduit member,

means for removabljv clamping one cnd ol said member with said jacket, and means 'or removably clamping the other end o1' .Laid member with .said pump.

4. rl`he combination will a motor vehicle engine provided with a pump, a gem-rater. and a c vlinder water jacket., ot` a pivotal mounting for the pump and generator wherebjy the two may be adjusted as; a unit with respect to the cylinder water jacket, and a connection between the pump and the Ywater jacket, the said connection including a llexible member perniitting adjustment ol' the pump and generator about their pivot.

The coml'iination with a motor vehicle provided with a pump. a generator, and a cylinder' water jacketj ol a pivotal mourning for the said pump, and generator' wheiwbj the two may be adjusted as a unit with rcspect to the cylinder water jacket. and a connection between the said pump and the Said jacket including a collapsible, bellow like conduit member permitting the movement of the said pump and generator toward and away from the said jacket.

G. The combination with a motor vehicle engine having a cylinder water jacket and provided with a pump and generator. ol' means lor adjusting the pump and generator as a u nit with respect to the cylinder water jacket, and means tor detachabijv conlu-,ctingI the pump to the water jacket to `l'orm a con-- duit therebetween, the said means` permittingmovement ot the pump relative to the water jacket.

In testimonj1 whereof I aflix my signature.
